If you’re looking into information about trying to conceive and your fertility, you may have come across the letters A-M-H. Those letters stand for anti mullerian hormone, a hot topic in the medical community right now. Research is showing that AMH levels can help determine ovarian reserve quality, but there is a push for more research to be done.
Knowing your anti-mullerian hormone levels can be an important step in your fertility journey. It can allow your provider some insight into what may be preventing you from conceiving, allowing a plan to be created to help you along your fertility journey. Let’s take a look at what exactly AMH is and why it may be important for you to look into.
What is AMH?
AMH stands for anti mullerian hormone. AMH plays a very important role in the regulation of ovarian follicle growth. AMH levels can help a doctor determine egg count. According to Advanced Fertility, “AMH blood levels are thought to reflect the size of the remaining egg supply – or “ovarian reserve””. It used to be referred to as “mullerian inhibiting substance” or “MIS”.
What is a typical AMH?
The typical AMH in a fertile person is 1.0-4.0 ng/ml.
Dr. Nataki Douglas of Modern Fertility recommends testing once, then again in about 12 months. When you should consider retesting depends on your age, your AMH level, and how it is changing over time.
Why would you test your AMH?
AMH testing can be used to determine the start of menopause, determine reasons for early menopause, find out the reason for lack of menstruation (amenorrhea), diagnose poly-cystic ovarian syndrome (PCOS), check infants with genitals that can not be determined as male or female at birth, and to monitor ovarian cancer. It is often used to diagnose amenorrhea in females younger than 15 and to diagnose PCOS in those trying to conceive.
You may want to request an AMH test if you are experiencing decreased breast size, weight gain, facial and body hair growth, acne, and menstrual disorders or irregular periods. You may also need testing before beginning IVF (in vitro fertilization).
It is important to know that AMH levels can fluctuate. Your levels right now are not an end all on if you are able to conceive. That is why it is important to track AMH.
Fertility begins to decline up to 10 years before menopause and the average age of menopause is 51. By 41 fertility is already taking a major decline. With so many people waiting longer to start a family, AMH is becoming more important to monitor in order to be successful in your pregnancy journey. It may determine if someone chooses to start a family earlier rather than later.
What to know about low AMH
What to know about high AMH
Some research has shown taking micronutrients present in Impryl can increase AMH. Poor nutrient absorption can contribute to low AMH, as seen in people with Crohn’s disease. It is important to consult with specialists if you have an autoimmune disease because treating your autoimmune disease, if possible, may improve your AMH levels. The Journal of Human Reproductive Sciences published a study showing increased AMH when people began exercising moderately. There is no conclusive evidence of if AMH levels can be increased, but proper diet and exercise can prepare your body for a healthier pregnancy.
IVF and AMH
AMH can help you understand how many eggs may be extracted during egg retrieval for egg freezing and IVF. Your AMH levels may be checked during your initial lab work when pursuing IVF. These levels can determine if you are a good IVF candidate. In IVF patients high AMH levels correlate with low cancellation rates, retrieval of more eggs, higher live birth rates and a high chance for freezing of leftover embryos. Research shows no difference in success for patients with low vs extremely low AMH. Age is a key factor in the success of IVF.
Past Pregnancy Delivery Mode
There has not been a connection found thus far between type of delivery and AMH levels. A past cesarean section would not impact levels over a vaginal delivery.
Birth Control and AMH
The oral birth control pill has been shown to lower AMH levels temporarily. This differs brand to brand and person to person. It is important to consult with your doctor when making decisions about which birth control option is best for you and for your future fertility goals.
Testing is usually conducted via a standard blood sample. Testing can be conducted at home with kits like the Modern Fertility Hormone Test.
Throughout trying to conceive there are so many questions people want to ask and they want detailed answers. People do not want a “we just don’t know” type of answer from their provider, which is why further research is so important. People deserve to know what is going on in their body. It can be hard to know what to ask when consulting with a provider and in lots of cases, if you don’t ask they might not tell you something you wish you had known. Anti mullerian hormone is a key term to know when trying to conceive, especially for those of us experiencing infertility. Remember that you can always ask your provider if AMH testing is right for you, order an at home test, or consult with other providers if you think AMH testing could bring you a clearer picture of what is happening inside your body.
